55098c5c61 bnx2x: Add remote-fault link detection
Restore remote-faule detection, which periodically checks for
remote-fault on the MAC layer. In case physical link appear to be
up but fault is set, it will provide a link down indication, and
when the fault is cleared, it will indicate link up again.

30a5de7723 bnx2x: added support for working with one msix irq.
Until now, the bnx2x driver needed at least 2 available msix interrupt
vectors in order to use msix. This patch add the possibility of configuring
msix when only one interrupt vector is available.
Notice this patch contains lines with over 80 characters, as it keeps print
strings in a single line.

33be96e47c net/hyperv: Add flow control based on hi/low watermark
In the existing code, we only stop queue when the ringbuffer is full,
so the current packet has to be dropped or retried from upper layer.

This patch stops the tx queue when available ringbuffer is below
the low watermark. So the ringbuffer still has small amount of space
available for the current packet. This will reduce the overhead of
retries on sending.

7d26bb103c bonding: emit event when bonding changes MAC
When a bonding device is configured with fail_over_mac=active,
we expect to see the MAC address of the new active slave as the source MAC
address after failover. But we see that the source MAC address is the MAC
address of previous active slave.

Emit NETDEV_CHANGEADDR event when bonding changes its MAC address, in order
to let arp_netdev_event flush neighbour cache and route cache.

How to reproduce this bug ?

                       -----------hostB----------------
hostA ----- switch ---|-- eth0--bond0(192.168.100.2/24)|
(192.168.100.1/24  \--|-- eth1-/                       |
                       --------------------------------

1 on hostB,
modprobe bonding mode=1 miimon=500 fail_over_mac=active downdelay=1000
num_grat_arp=1
ifconfig bond0 192.168.100.2/24 up
ifenslave bond0 eth0
ifenslave bond0 eth1

then eth0 is the active slave, and MAC of bond0 is MAC of eth0.

2 on hostA, ping 192.168.100.2

3 on hostB,
tcpdump -i bond0 -p icmp -XXX
you will see bond0 uses MAC of eth0 as source MAC in icmp reply.

4 on hostB,
ifconfig eth0 down
tcpdump -i bond0 -p icmp -XXX (just keep it running in step 3)
you will see first bond0 uses MAC of eth1 as source MAC in icmp
reply, then it will use MAC of eth0 as source MAC.

34800598b2 ARM: driver specific updates
These are all specific to some driver. They are typically the platform
 side of a change in the drivers directory, such as adding a new driver
 or extending the interface to the platform. In cases where there is no
 maintainer for the driver, or the maintainer prefers to have the
 platform changes in the same branch as the driver changes, the patches
 to the drivers are included as well.
 
 A much smaller set of driver updates that depend on other branches
 getting merged first will be sent later.
 
 The new export of tegra_chip_uid conflicts with other changes in fuse.c.
 In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with
 the cleanup of the interrupt handling of that driver.

Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: driver specific updates" from Arnd Bergmann:
 "These are all specific to some driver.  They are typically the
  platform side of a change in the drivers directory, such as adding a
  new driver or extending the interface to the platform.  In cases where
  there is no maintainer for the driver, or the maintainer prefers to
  have the platform changes in the same branch as the driver changes,
  the patches to the drivers are included as well.

  A much smaller set of driver updates that depend on other branches
  getting merged first will be sent later.

  The new export of tegra_chip_uid conflicts with other changes in
  fuse.c.  In rtc-sa1100.c, the global removal of IRQF_DISABLED
  conflicts with the cleanup of the interrupt handling of that driver.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fixed up aforementioned trivial conflicts.

643c61e119 rtlwifi: rtl8192ce: rtl8192cu: rtl8192de: Fix low-gain setting when scanning
In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit a9b89e2) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.

Driver rtl8192de also has the same code structure - this one is fixed as well.

4e808a38fd rt2x00: rt2800usb: fix status register reread logic
Another good catch from Jakub Kicinski. This patch fixes my
recent commit: ed61e2b02027935520d1be884fac0b2ffce8379a
"rt2x00: rt2800usb: rework txdone code"

We should reread status register only when nobody else start already
reading status i.e. test_and_set_bit(TX_STATUS_READING, flags) return 0.

b9fc106108 rt2x00: rt2800usb: schedule txdone work on timeout
This is fix for my current commit
ed61e2b02027935520d1be884fac0b2ffce8379a
"rt2x00: rt2800usb: rework txdone code"

We should schedule txdone work on timeout, otherwise if newer get
tx status from hardware, we will never report tx status to mac80211
and eventually never wakeup tx queue.

b5447ff92b ath9k: fix a memory leak in ath_rx_tasklet()
commit 0d95521ea7 (ath9k: use split rx buffers to get rid of order-1 skb
allocations) added in memory leak in error path.

sc->rx.frag should be cleared after the pskb_expand_head() call, or else
we jump to requeue_drop_frag and leak an skb.

195ca3b122 ath9k: reduce listen time period
When we have downlink traffic alone and the station is going thru
bgscan, the client is out of operating channel for around 1000ms which
is too long. The mac80211 decides when to switch back to oper channel
based on tx queue, bad latency and listen time. As the station does not
have tx traffic, the bgscan can easily affect downlink throughput. By
reducing the listen time, it helps the associated AP to retain the
downstream rate.

e92109be7a iwlegacy: fix BSSID setting
Current commit 0775f9f90cdaf40fbf69b3192b3dddb2b3436f45
"mac80211: remove spurious BSSID change flag" exposed bug on iwlegacy,
that we do not set BSSID address correctly and then device was not able
to receive frames after successful associate.

On the way fix scan canceling comment. Apparently ->post_associate()
do cancel scan itself, but scan cancel on BSS_CHANGED_BSSID is needed.
I'm not sure why, but when I removed it, I had frequent auth failures:

 wlan4: send auth to 54:e6:fc:98:63:fe (try 1/3)
 wlan4: send auth to 54:e6:fc:98:63:fe (try 2/3)
 wlan4: send auth to 54:e6:fc:98:63:fe (try 3/3)
 wlan4: authentication with 54:e6:fc:98:63:fe timed out
